Does Kyle, TX need an earthquake retrofit?

Under the seismic model IBC and ASCE 7 use for new construction, Kyle is Category A. Lowest seismic design category. Building code requires no seismic-specific detailing here beyond ordinary construction practice. Rank it against the rest of the country and Kyle sits at the 7th percentile for seismic hazard among 4,875 US cities.

Outside California, earthquake coverage is typically sold as an endorsement added to a standard homeowners policy, not a separate product - worth asking about directly when getting a home-insurance quote for a Kyle address.
